RAELROAD-B-AIIrSCALING MACHINE.

Application filed January 11, 1926.

Before placing railroad rails in the furnace, it is desirable that the scales be removed from the head thereof, and in order that this may be accomplished in a rapid and economical way the machine illustrated in the accompanying drawings has been designed.

i Vhile the drawings illustrate a preferred embodiment of the invention it is to be understood that in adapting the means to meetspecific needs and requirements the design may be varied, and such other changes in the minor details of construction may be resorted to within the scope of the invention as claimed, without departing from the spirit thereof.

For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawings hereto attached in which,

Figure 1 is a side view of a machine for removing the scale from railroad rails constructed in accordance with and embodying the essential features of the invention,

Figure 2 is an end view of the machine, the rail being; in section,

Figure 8 is a detail perspective view of the toothed end of one of-the files, and

Figure 4 is a perspective view of one of the chisels.

Corresponding and like parts are referred to in the following description and designated in the several. views of the drawings by like reference characters.

The operating parts of the machine are mounted upon a suitable frame work which includes a table and supporting legs, the table being comprised between spaced longitudinal rails 1 which are secured to legs 2. Rolls 3 and 4 are located at opposite ends of the table and are journaled in the rails 1, and are adapted to be positively driven to feed the rail 5 from which the scale is to be removed. Standards 6 are located at one side of the table and project upwardly to a suitable distance so as to support a crank shaft 7 at a proper elevation to insure effective action of the file, or other scale removing tool. The crank portions of the shaft 7 are disposed so as to advance certain files and, at the same time, return other files to an initial, or operative position, there being an equal number of files which are arranged so that while a certain number of Serial No. 80,658.

files are performing work on the advance stroke, a like number are returning to an initial position preliminary to the next advancing, or working stroke. A suitable motor 8 is provided and is mounted upon a stand 9 and geared to the crank shaft to drive the same. A pinion 10 fastto the drive shaft of the motor 8 is inmesh with a wheel llfast to the crank shaft 7.

The feed rolls 3 and 4c derive movement from the crank shaft 7, this being effect-ed by means of a drive belt 12 passing around a pulley 18 applied to the crank shaft 7 and a pulley fast to transverse shaft 1 1- and which pulley is connected to pulleys fast to the shaft of the respective feed rolls by drive belts 15 and 16. Obviously, the feed rolls 3 and 4. may be driven in any preferred way.

A plurality of files, or scale removing tools are provided and each is mounted upon a crank portion of the shaft 7, so as to be actuated thereby. Each of the files comprises a shank 17, a head 18 and a projection 19. The head 18 is toothed, as indicated at 20, and operates by an approximate horizontal reciprocatorv movement. The shank 17 is inclined to the head 18 and is journaled up on a crank portion of the shaft 7. The projections 19 constitute stops.

Ghisels are located at opposite ends of the machine and are inversely disposed, as shown most clearly in Figure 1. Each of the chiselscomprises a body 21 and a point 22 which tapers to a cutting edge, shaped transversely to conform side of the head of the rail 5. A shaft 23 is journaled in a standard 24 and has arms 25 and 26, the latter being connected to the chisel and the arm 25 constituting an operating handle, whereby the chisel may be raised or lowered as desired, in the operation of the machine. The chisels 21 are arranged with their cutting ends facin inwardly and, as a result, one of the chisels only, is in operative position to remove the scales from the rail.

Dsiplacement of the rail 5 from the table of the machine is prevented by a retainer which, as shown, consists of a rod 27 and a hook 28 at the upper end of the rod, said hook engaging over the foot of the rail, as shown most clearly in Figure 2. For conveniently operat g the retainer, a treadle to the contour of a 29 is provided and is connected at one end to the rod 27 and its opposite end portion is adapted to coaet with a toothed bar 30, whereby the retainer may be held in the required adjusted position.

When reversing the rail 5, or placing new rail in position to be operated upon, it is desirable to support the tiles for this purpose, a bar 31 is employed, and coil springs 32 connect the bar 31 with the standards 24: and when the bar 31 is elevated, it engages the outer ends of the files to support the same clear of the rail 5. When the bar 3]. is not in active operation it is depressed and held in lowered position by suitable fastening means, as hooks 33.

In the operation of the machine, a rail 5 from which the scale is to be removed is placed upon one of the feed rolls 3 or L, and is advanced thereby to the table and during this movement, one of the chisels operates remove the scale from the lower edge of the rail. lVhen the shaft 7 is in action the tiles receive a transverse reciprocatory movement and the toothed portions operating upon the rail loosen and remove the scale therefrom. As the rail 5 moves over the table of the machine, the scale is removed from one side only and the rail is reversed and in moving over the table in the opposite direction the scale is removed from the opposite side. It Will thus be understood that only one of the chisels is in operation at a time. The rails 5 travel across the table continuously and are prevented from displacement and tilting by the hook 28. If found necessary more than one hook 28 may be provided and applied to each of the legs 2. It is rarely necessary to reverse the machine and to meet this contingency the two sets of chisels are provided.

Having thus described the invention, I claim:

1. In a machine for removing scales from a railroad rail, means for supporting the rail, a chisel arranged to operate longitudinally of the rail, a plurality of transversely arranged scale removing tools and means for imparting a reciprocatory movement to the said scale removing tools.

In a machine for removing scale from railroad r ils, oppositely disposed scale moving chisels spaced apart and disposed to operate longitudinally of the rails, transversely a1 anged scale removing tools located intermediate the said chisels and means for imparting a reciprocatory move-- ment to said scale removing tools.

In a machine of the character specified. rail supporting means, a crank shaft paralleling the rail supporting means and a plurality of scale ren'ioving tools mounted upon the crank portions of said crank shaft.

In a machine of the character specified, rail supportingmeans, a crank sn ll leling the rail supporting means and a pit.- rality of scale removing tools mounted upon the crank portion of said crank s raft and a bar yieldably mounted and adapted to engage and support the scale removing tools when removing, or replacing a rail.

5. A. machine for removing scale from railroad rails, the same comprising rail support ing means, feed rolls at the ends of the rail supporting means, oppositely disposed scale removing chisels, a crank shaft and scale re moving tools mounted upon the crank portions of the crank shaft and disposed intermediate the scale removing chisels and adapted to operate transversely of the rail.

6. A machine for removing scale from railroad rails, the same comprising rail supporting means, feed rolls at the ends of the rail supporting means, oppositely disposed scale removing chisels, a crank shaft and scale removing tools mounted upon the crank portions of the crank shaft and disposed intermediate the scale removing chisels and adapted to operate transversely of t ne rail, a retainer adapted to engage and hold the rail in place and a treadle for operating said retainer.

In testimony whereof I affix my signature.
